This is an early vertical space shooter game. You must destroy all aliens and a special monster that sometimes appears on the screen.
Cheats / Tricks / Bugs / Easter Eggs
If you destroy all the smaller aliens but one, that last alien will turn into the 'special monster' - a giant gargoyle which is named Bagle. Bagle will then dive bomb the player. Bagle can be destroyed after one hit, as he's really only faster and bigger than the smaller aliens.
Fight the three types of aliens that appear in the different levels. The longer you play the more aliens will fly down to you dropping deadly bombs. Some aliens fly together in a formation making a cool jet sound.
